BACKGROUND OF THE INVENTION

TNF-related apoptosis-inducing ligand (TRAIL; Apo2L) is an endogenousprotein that selectively induces apoptosis in cancer cells. TRAIL is apowerful inducer of apoptosis in a wide range of human cancer cell linesvia pro-apoptotic death receptor 4 (DR4; TRAIL-R1) and death receptor 5(DR5; TRAIL-R2) at the cell surface through engagement of the extrinsicor intrinsic apoptotic pathways. TRAIL plays a direct role in tumorsuppression during immune surveillance but this anti-tumor mechanism islost during the disease progression. The ability of TRAIL to initiateapoptosis selectively in cancer cells has led to ongoing clinical trialswith administration of recombinant TRAIL and the longer-livedTRAIL-agonist antibodies targeting either of its two pro-apoptotic deathreceptors.

Despite its potency, recombinant TRAIL has efficacy-limiting propertiessuch as short serum half-life, stability, cost, and delivery. Deliveryof recombinant TRAIL or TRAIL-agonist antibodies to the brain is limitedby inability of recombinant TRAIL and TRAIL-agonist antibodies to crossthe blood-brain barrier. Accordingly, there is a continuing need foranti-cancer compositions and methods.

In some embodiments, treatment of cancer comprises prevention of tumorgrowth in a cancer subject. In some embodiments, treatment of cancercomprises prevention of formation of cancer metastases in a cancersubject. In some embodiments, treatment of cancer comprises targetedtreatment of minimal residual disease in a cancer subject known to havethe minimal residual disease in a cancer or a subject at risk for havingminimal residual disease.

This might be indicated after treatment of the primary tumor by surgeryand/or after chemotherapy (e.g. radiotherapy) has been initiated ordetermined to efficacious. Disseminated tumor cells may be in theirdormant state and often cannot be attacked by the chemotherapy(radiotherapy). A thus treated patient seemingly is in a healed state,which is also described as “minimal residual disease”. Nevertheless, thedormant tumor cells have a potential of forming metastases if theybecome metastasising cells due to a growth stimulus also after a longerdormant state.

As used herein, “minimal residual disease” denotes a small number ofcancer cells that remain in a subject during treatment, or aftertreatment when the subject is in remission (exhibiting no symptoms orsigns of the disease).

While agitating the reaction mixture, 1 N HCl indioxane-MTBE solution was added dropwise (4 N HCl in dioxane: 300 mL,1.2 mol, 2.27 equiv; MTBE: 1200 mL) until no more solid precipitated outof the reaction mixture upon addition of HCl. The reaction mixture washeated to reflux at 60-65° C. for 2 hours. Water was separated into theDean-Stark trap as necessary. Upon cooling to room temperature, thesolid precipitate was filtered through a sintered glass funnel andwashed with n-butanol-MTBE (1:2, 600 mL) and MTBE (600 mL) respectively.The solid was dried in the vacuum oven at 65° C. overnight (16 hours) toafford 200 g yellow solid.

To a 2 L three-neck round bottom flask equipped with mechanicalstirring, N2 inlet, a thermocouple and a condenser, the above solid (200g) was added, followed by ethanol (1000 mL). The mixture was heated toreflux at 78° C. for 2 hours. Upon cooling to room temperature, thesolid was filtered through a sintered glass funnel and washed withethanol (200 mL×3). The wet solid was dried in the vacuum oven at 85° C.for 3 days until the residual solvent met specification. 120 g ofcompound (2) was obtained as a white solid in a yield of 49%, with HPLCpurity 99.7%.
